This PhD project in Ecology is funded by the Swiss National Science Foundation and will be based at the Institute of Evolutionary Biology and Environmental Studies (IEU). The Aldabra Atoll in the Western Indian Ocean is a UNESCO World Heritage Site and home to 100,000 giant tortoises (Aldabrachelys gigantea) – the largest surviving population of giant tortoises in the world. The project aims at dramatically improving our understanding of the role of the giant tortoises as seed dispersers. We will investigate multiple levels of ecological organisation, from individual behaviour and the outcome of pairwise interactions, to community-level interaction patterns. Leer más.
